I need a skilled Symfony developer to take my existing application to its next stage. The current build runs well but now requires a broader update that touches three fronts at once: • New capabilities: implement robust user authentication (registration, login, role-based access), wire the app to an external REST API, and build a lightweight custom CMS so team members can manage content without touching code. • Performance boost: profile bottlenecks, refactor slow queries or services, and apply Symfony-friendly caching so page loads stay consistently fast, even after new features land. • Visual refresh: update the design layer to a clean, responsive UI. Feel free to recommend Twig, Stimulus, Tailwind—or another modern stack that pairs smoothly with Symfony—so long as the final result looks sharp on both desktop and mobile. I will provide full repository access, a staging server, and all API documentation. Please share links to comparable Symfony work, outline the steps you’d follow, and estimate how long you expect the migration, feature work, and UI overhaul to take. Clean, well-commented code that passes existing tests is a must; adding new tests for the features you introduce will be appreciated. If you enjoy improving real-world Symfony apps and can collaborate closely over Git, let’s talk.
